Abstract: For short of criterions, traditional safety monitoring was based on the size and importance of slope, that among all cross sections, the more important the cross section was, the more monitoring items and instruments. But for large and complex slope, dynamic informationization design was always demanded, so that dynamic monitoring was necessary. Classificated monitoring is of the advantage that it may not only cover full scale but also stress on key parts. By application of dynamic adjustment, the purpose of rationality and pertinency was achieved, and furthermore, it may provide important data for dynamic informationizaiton management.
